description A composition for saturation of preformed, previously cured foam substrates having an at least partially open cell configuration, includes a polymer binder in which microspheres containing a phase change material are dispersed. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. A preferred cured foam substrate is a skived polyurethane or polyether foam of from 20 to 1,000 mils in thickness, preferably 20 to 200 mils in thickness, having up to 6 ounces per square yard or more of encapsulated phase change material embedded in a polymer binder. One method of applying the binder with dispersed encapsulated phase change materials is by applying a binder/microsphere dispersion to the upper surface of a previously cured foam sheet, then drawing a vacuum from the underside of the cured foam sheet to permeate from 20 % to 100 % of the cured foam sheet with the binder/microsphere dispersion. The resulting product is then cured. An alternative method of applying the binder with embedded encapsulated phase change materials using knife over roll technique to an exposed surface of the skived foam is disclosed in which the most preferred viscosity of the uncured polymer binder is from 7,000 to 9,000 centipoise. L'invention concerne une composition pour saturer des substrats de mousse préformés, durcis au préalable, présentant une configuration à cellules au moins partiellement ouvertes. Cette composition comprend un liant polymère dans lequel sont dispersées des microsphères contenant un matériau à changement de phase. De préférence, on utilise des hydrocarbures paraffiniques comme matériaux à changement de phase. Les microsphères peuvent être microencapsulées. Un substrat de mousse durci préféré est constitué par une mousse de polyuréthanne ou de polyéther taillée en biseau, présentant une épaisseur comprise entre 20 et 1000 millièmes de pouce, de préférence entre 20 et 200 millièmes de pouce, contenant jusqu'à 6 onces par yard carré, ou davantage, de matériau à changement de phase incorporé dans un liant polymère. Un procédé d'application du liant avec des matériaux à changement de phase, encapsulés, dispersés, consiste à appliquer une dispersion liant/microsphères à la surface supérieure d'une feuille de mousse durcie au préalable, à faire le vide à partir de la face inférieure de la feuille de mousse durcie afin d'imprégner 20 % à 100 % de la feuille de mousse durcie avec la dispersion liant/microsphères.
